Apnlication filed July 25,

T 0 all whom it may concern Be it known that we, CHARLES F. Loon- HART and Evnimrr H. Boer, citizens of the United States, residingat Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in WVashing-Machine Founders, of which the following is a specification.

This invention relates to suction cups,

stated. When used, the action of this cup is to first compress the clothes; then the piston in the neck of the cup forces the air and water in the cup through the clothes. The cup continues to be held with pressure against the clothes by means of a spring in the neck of the cup, and when the piston is moved upward there is a vacuum action which draws the water-back through the clothes in the opposite direction, and at the same time the suction causes the clothes to adhere to the mouth of the cup until they are lifted up in the water, permitting the water from the surrounding part to rush in under the clothes, and on the next stroke the cup is forced down, carrying the clothes with it, and then the piston descends and the operation above described is repeated. This action results in a very powerful cleaning effect on the clothes and produces a superior washing action.

In the accompanying drawing Fig. 1 is a vertical section of one of the cups. Fig. 2 is a section on the line 22 of Fig. 1.

Referring specifically to the drawing, 6 indicates a dasher head or spider which carries the cups, a part only of this element being shown, as a plurality of cups are or will be attached thereto. The cup proper is indicated at 7 consisting of a frusto conical member, preferably made of sheet metal, and having an outstanding flange 8 at the mouth or bottom. At the top the cup is formed with a sleeve 9 forming a cylinder or barrel which reciprocates on a hollow plunger 10 the head of which may have a leather packing indicated at 11 to make it water tight, this packing being fastened to the head of 1921. .SeriatNo. 487,388.

Then the plunger'picks up the cup and the clothes adhere thereto and are lifted with the cupto the top of the water in the tub or thereabouts. Then the plunger again descends and the operation is repeated. There are thus four separate actions at each complete stroke of the dasher: the first is the cup compression against the clot-hes; the sec ond isthe piston action of the plunger in the barrel, forcing the water downwardly through the clothes; the next is the piston action when the plunger lifts,'thereby suck ing the water up through the clothes; and finally the lift of the cup and'the clothes adhering thereto. This produces a veryfsu perior cup for the intended purpose.

We claim: 1. The combination with a dasher, of a hollow plunger attached thereto and depend ing therefrom, the lower end of the plunger being closed, a suction cup having a barrel at the top in which theplunger fits slidably, and a spring enclosed within the plunger and operatively connected to the barrel and tending to force the cup downwardly.

2. A device of the kind described com-v prisinga suction cup having a barrel at the top thereof, a slotted plunger movable up and down in the barrel and adapted to be connected to a dasher, a cross piece connected to the barrel and extending through the plunger, and a spring in compression bevtween the cross piece and the plunger.

3. A device of the kind described comprising a suction cup having a pump barrel at the top a hollow plunger working in said barrel, said plunger having slots in its side walls a dasher connected to the upper end of the plunger a rod extending through the slots and connected to the barrel and a spring enclosed in the plunger and confined between the upper end thereof and the said rod.

,In testimony whereof, we afiiX our signatures in presence of two witnesses.
